A connecting seat 25, these Connection Block 25 1 ends are provided with protuberance 253, and this protuberance 253 is the taper projection again, and the protuberance 253 of this Connection Block 25 can be inserted in the needle stand 23 in the syringe 2, and this Connection Block 25 is provided with one by card division 252 again, and this Connection Block 25 is provided with waveform protuberance 251.
Pipe 3 in one, pipe 3 at least one sides are provided with sliding ditch 31 in this, and pipe 3 is provided with hollow bulb 311 in being somebody's turn to do again; Be provided with an elastic component 33 in this hollow bulb 311, should be provided with sliding part 34 by interior pipe 3, this sliding part 34 and elastic component 33 1 end sockets again; Make elastic component 33 1 ends and sliding part 34 butts, the front end of the other end and interior pipe 3 offsets, and is provided with holding section 342 in this sliding part 34 again; And this holding section 342 can with being fastened of Connection Block 25 by card division 252; And these sliding part 34 1 ends are provided with projection 341, this projection 341 can be in sliding ditch 31 sliding transfer, and this projection 341 can offset with the protuberance 212 of syringe 2 rear ends and ends; Should be provided with button lid 35 by interior hollow bulb 311 of managing 3 rear ends 352; Should be arranged with rubber neck 32 by interior pipe 3 front ends 351 again, this rubber neck 32 is the annular hollow shape, and hollow bulb 311 inwalls of the front end 351 of pipe 3 can be abutted against with the waveform protuberance 251 of Connection Block 25 mutually in being somebody's turn to do.
Please consult shown in Figure 6ly again, when standard pin 22 extracted liquid medicine 5, pipe 3 will receive a pulling force 4 backward in this; This moment should in pipe 3 just can drive Connection Block 25 and push elastic component 33 backward, after extracting liquid medicine 5 and finishing, just can being fastened of this Connection Block 25 1 ends with the holding section 342 of sliding part 34 by card division 252; And compression elastic piece 33 and as shown in Figure 7, when pipe 3 in this receives when executing hitter's thrust 6 forward actions, liquid medicine 5 just is injected in by standard pin 22 and is executed on one's body the hitter; And when injection finishes; See also shown in Figure 8ly, pipe 3 is abutted against with rubber stopper 24 because of thrust 6 once more mutually in this, and the protuberance 253 of this Connection Block 25 just can with the driving fit mutually of needle stand 23 1 ends.
Please consult shown in Figure 9 again; When injection finishes will needle stand 23 be reclaimed automatically the time; At this moment standard pin 22 has been connected with needle stand 2 and connecting portion 25, just can continue in this pipe 3 and apply an inside external force 7, and when this acts in, manage 3 external force 7 when applying; Oblique cone radian 213 in this pressure part 21 just can be pushed because of rubber stopper 24; Cause pressure part 21 front ends outwards to support 71 and open, this moment is as long as press 8 nearly breaches, 215 places in these pressure part 21 usefulness handss again, and then these pressure part 21 front ends just can be supported 81 more hold once more by Access Division 214; And make pressure part 21 broken away from the Access Division 232 of needle stands 23 by Access Division 214; Half thread 2111 with the projection of standard pin 22 222 and connecting hole 211 is screwed to the end simultaneously, and it is separated with connecting hole, make this standard pin 22 can by pressure part 21 supported by Access Division 214 81 breach that come come through and shown in figure 10; And can just can be fastened by these Connection Block 25 1 ends with the holding section 342 of sliding part 34 by card division 252; And the elastic force that sliding part 34 receives elastic component 33 slides backward displacement (at this moment standard pin 22 has been connected with needle stand 2 and connecting portion 25), and in can standard pin 22 being recycled in the hollow bulb 311 of pipe 3, thereby reach the function that needle stand reclaims.
This utility model is provided with pressure part 21 by this syringe 2, and after this syringe 2 finishes using, because of pressure part 21 front ends also do not support out; Make standard pin 22 also fail to reclaim, breach 215 places of at this moment pressing 8 pressure parts 21, pressure part 21 front ends just can be supported again by Access Division 214 81 more come; So that make standard pin 22 to pass through, therefore just can trigger elastic component 33, needle stand 23 is recovered in the syringe 2 automatically; Improving safety guarantees; Moreover, when not using, this elastic component 23 keeps free state, and can be because of the purpose of the flexible tired problem that is squeezed.
For making this utility model show its progressive and practicality more, following with one comparative analysis of existing do now:
Prior art:
1, spring is in compressive state for a long time when not using, and therefore is prone to cause the back-moving spring elastic fatigue, and the inconvenience that can't smoothly elasticity reset device be rebounded.
2, easily because of external force touches back-moving spring, make entry needle also from not taken out by being executed the hitter on one's body, promptly, cause being executed the hitter also with the hemostasis of hemostasis Cotton Gossypii because of the rebounding of back-moving spring, promptly caused and executed the danger that hitter's blood has overflowed.
This utility model advantage:
Keep free state when 1, this utility model does not use because of spring, therefore solve the problem of existing elastic fatigue.
2, this utility model is executed the hitter on one's body the time in injection, can press by, the purpose of guaranteeing with improving safety because of pressure part is arranged.
